France should just socialize the indexing of web content from their ip ranges. They should make it illegal to index the range. Then sell the index to search providers. (with a limited license that they can revoke)

DMCA is a result of a treaty between the USA and Germany. A treaty that was approved by both elected governments. France should push for a global censorship treaty if they want to effect American search results.

publish == broadcast. In the USA publishing a work grants you copyright. You have copyright over what you publish on Twitch (assuming it not derivative work) Everything written on the internet is copyrighted. Including this comment. Fair Use exemptions and the terms of use you agreed to when you clicked Submit is why you have a license to read comments. Terms of use is why you can view content on Twitch. But the copyright still exists. You can't take someone Twitch content and then sell it.

It has been true prior to the invention of the internet. Businesses have been keeping personal data on customers for thousands of years. That data is always part of the sale of the company. Companies buy each other to get the other companies customers. You can't purchase customers without transferring customer data. Management of a company can change at any time. So even if the name on the site doesn't change your data may wind up in the hands of new people.

According to the Chief Justice their are multiple drafting mistakes in the law. So number 1 was decided in court by 6 experienced Judges. Number 2 does not make any sense. If they wanted to force states to setup their own exchanges they would not provide the federal option at all. Your interpretation is also likely unconstitutional. (Federal Government is required to treat citizens the same regardless of what state they live in.)

If Congress wants to repeal the law then they should go and do that. Congress can change the law whenever it wants. It isn't the Supreme Courts job to ignore 99% of the text of a law and toss out laws they don't like because of typos.
